True, but if somebody is having trouble with it, then they would be better off getting 8, where the support is included, kernel editing, can be stressful if you don't have a lot of experience with it. Then best choice would be to get the update from redhat.com or to just get rh8. Kernel modifications are can be cofusing sometimes, and if you make some mistakes, well, you can end up having caused more problems than you created. Of course, all the support that red hat offers is built into the kernel, but kernels can be easily updated from the rh site.
